Hello! 3x + 20 and 8x - 5 are equal. To find the value of "x", we should set up and solve an equation. It would be written like this:

3x + 20 = 8x - 5

First off, subtract 3x from both sides in order to get 20 = 5x - 5. Add 5 to both sides to get 25 = 5x. Now, divide each side by 5 to isolate the "x". 25/5 is 5. Now, let's plug in the value and see if it works. 3 * 5 is 15. 15 + 20 is 35. 8 * 5 is 40. 40 - 5 is 35. 35 = 35. There. x = 5.

The area of a rectangular raised garden bed for growing beets is given by the expression(3b)(3b-3). The length, l, of the mat is

mars1129 [50]

Answer:

C and D

Step-by-step explanation:

The area of a rectangular raised garden bed for growing beets is given by the expression $(3b)(3b-3).$

The area of the rectangle is

$A=\text{Width}\cdot \text{Length}$

Thus,

$\text{Width}=3b\\ \\\text{Length}=3b-3$

or

$\text{Width}=3b-3\\ \\\text{Length}=3b$

The length of the mat is greater than its width. Since

$3b>3b-3$

then

$\text{Width}=3b-3\\ \\\text{Length}=3b$

Options A and B are false, options C and D are true.

Ariel needs to paint the trim of a triangular box. If A (-2,4), B (2,2), and C (-1, -2) are the vertices of the triangle, what i

Kisachek [45]

Total length of the trim painted is 15.75 unit.

<u>Given:</u>

Co-ordinate of point A = (-2,4)
Co-ordinate of point B = (2,2)
Co-ordinate of point C = (-1,-2)

<u>Find:</u>

<em>Total length</em> of the trim painted

<u>Computation:</u>

Distance between two point = √(x1 - x2)² + (y1 - y2)²

Distance between AB = √(-2 - 2)² + (4 - 2)²

Distance between AB = √16 + 4

<em>Distance between AB</em> = 2√5 unit = 4.47 unit

Distance between BC = √(2 + 1)² + (2 + 2)²

Distance between BC = √9 + 16

<em>Distance between BC</em> = 5 unit

Distance between AC = √(-2 + 1)² + (4 + 2)²

Distance between AC = √1 + 36

<em>Distance between AC</em> = √37 unit = 6.08 unit

Total length of the trim painted = 4.47 + 5 + 6.08

Total length of the trim painted = <em>15.75 unit (Approx.)</em>
